Back in February, we reported about Peter Green's Mac mini portable project. Well, it looks like Peter has continued to make improvements and refinements to his design. The new Mac mini portable (MMP MkII) is built into a smaller enclosure and includes a flush-mounted trackpad, flush-mounted keyboard, USB Hub, and 8" TFT screen. Running off a 14.8 volt Li-on battery, the MMP MkII gets over three hours of battery life. Other new features include a front-mounted power button and dual-head display. You can see a video of the MMP MkII in action here.
